Today Appthority released the Q4 Enterprise Mobile Security Pulse Report. The report looks at three areas of interest to enterprise mobility and security teams: 1) the most common apps, 2) the apps most often blacklisted, 3) the most common mobile app data destinations and their reputations.

This quarter, we continued to see enterprises being exposed to data leakage and privacy risks from many commonly used apps and had some new additions to the top 10 lists of enterprise blacklisted apps.

For iOS devices, popular dating app Tinder made the list of most blacklisted apps, joining WhatsApp Messenger and Pokémon GO, which topped the list for the second consecutive quarter. For Android, the top blacklisted apps were WhatsApp Messenger, Facebook Messenger and Instagram, all new to the list from the previous quarter.

Most blacklisted Android and iOS apps had risk scores in the data leakage range (see the report for further scoring information). For Android, this was primarily due to sending data unencrypted. For iOS, this was for accessing the address book, camera and microphone, as well as tracking location and sending sensitive data unencrypted. Enterprises blacklist apps for a range of security concerns, including security policy compliance and concerns about data handling.

The Pulse report also lists the most common destination countries for mobile data and the reputation of the URLs used most by mobile apps among Appthority’s enterprise customers. Leading destination countries for the top Android and iOS apps are the United States, Ireland and Germany. This quarter, the United States, with over 85% of mobile app connections, saw the percent of trustworthy connections decline from 32% to 30.4% for Android connections and from 15% to 14.2% for iOS connections.
